Loud people in public places pretty much make me dislike them 100% of the time.
I know it's a right for anyone to say what they want and whatnot, but that doesn't mean that you can just go ahead and shout to each others' ears like you're the only ones in that place and while you don't give a shit, you are disturbing someone whether intentionally or unintentionally.

Usually the way they act around others. I can endure people who are annoying, but those who are arrogant, snobby, crude, indecent, or just downright nasty in their behavior to me or others makes me dislike them.

For example, there was this girl in high school that I was in class with from 2004 to 2008. She was beautiful, and at first glance appeared to be a sweet, gentle person that would be easy to get along with, but she had a terrible temper and snapped constantly at others. She ended up being a irritating, obnoxious jerk to just about everybody at school. Simply saying hello to her usually resulted in getting cussed out by her, and eventually everyone pretty much hated her by the end of our Senior Year due to how she treated everyone around her.

People who think cynical comments are smart, but they're just useless.

People love to sneak in hateful comments in all the time, and it really pisses me off when internet folks talk about fake people when at least 98% of crunchyroll is fake(No names) but they like to make fun of fakes?

Even though nobody would make low blow comments like this in real life, I don't do that, but these same people do, actually in a topic right below this one....

You have plenty of strong points, you can get points across really well,

Your communication is spot on, and you sound like a fun person, on the backside of your personally, I don't see why I wouldn't like you, Sure sometimes we clash in opinions but I do that a lot with people I love, hate, and neutral about, but that in NO way affects my thoughts about you as a person,
